IMPROVEMENT IN `MACHINERY FOR NAPPINGYCLOTIH.

Specification forming part of Letters Patent'No. 17,227, dated May 5,1857.

.To all whom it may concern:

Be it known that we, JOHN C. l\IILLAR,-of` Starucca, county ofSusquehanna, and State of Pennsylvania, and CHARLES N. TYLER, of

Vashington, in the District of Columbia, have invented certain new anduseful Improvements in Machines for Raising the Nap of Cloth, of whichthe following is a full, clear, and exact description, reference beinghad to the accompanying drawings `of the same, in which-` Figure lrepresents a viewin perspective of a machine embracing our improvements;

Fig. 2, a side elevation of the same, and Fig. 3 asimilar view of theother side of same. Fig.` 4.- represents an end elevation of the rear ofthe machine 5 and Fig. 5, a transverse ver- Y tical section of themachine through the lines 0c of Figs. 2 and 3, looking toward the rear Aof the machine.

Our improvement consists in the combination and arrangement of two ormore napping or teaseling cylinders in a horizontal plane,

whereby the cloth intended to be napped is submitted to the action oftwo or more sets of teasels each time it is caused to pass through themill, thus economizing time and labor.

Another and perhaps more important advantage arising from the use ofsuch a combination is that it enables the operator so to rotate thecylinders` as to teasel the cloth In opposite directions simultaneously,thereby1 materially hastening the process.

Notwithstanding the advantages arising from the combination of two ormore cylini the process is not only much hastened, but

the quality and finish of the cloth much irnproved. n

Our invention further consists In a new met-hed of securing thegig-rodsto which the teasels are attached to the cylinders, theyheretofore having been Inerely .slipped 'into the slides without anymeans being provided to retain them in their position, their tendencybeing to work loose, to the great damage both of the machine andcloth,to remedy which we cut a notch in one end of the rod of a widthsuflicient to embrace the shank of a screw-bolt in the head of thecylinder, the

head of the bolt retaining that end of the gigrod securely in itsposition, while the other is secured by means of a spring-plate pivotednear the center of the other cylinder-head, the upper side of that endof the gig-rod being confined between the lips of the guideplate; or,instead of a separate spring-plate for each, a disk having a series ofradiatingarms equal in number to the gig-rods may be mounted upon theshaft of the cylinder in such manner as to be free to be turned upon itsaxis, so that the gig-rods may be removed, replaced, and again secured,as may be desired.

In the accompanying drawings, A A represent the frame-work of themachine, upon the cross-beams of which are arranged and mounted insuitable bearings two hollowribbed cylinders I3 B in a horizontal plane,between the ribs of which are secured the gig-rods a, to which theteasels are attached, the gig-rod having for this purpose a notch Z9 cutin one end to embrace the shank of the bolt c, whose head confines thatend ofthe rod to the head of the cylinder, the other end of the rodbeing confined to the opposite head of the cylinder between the lips ofa bracket d, secured to the head and prevented from sliding outward by aspring-plate e, of which there are a series on every cylinder, one foreach gig-rod, the plates e in this instance being pivoted near and in aradial line with the shafts D of the cylinders, so that they may beturned aside and the rods withdrawn and turned back again when replaced.Between the two teaseling-cylinders B, but

so arranged as to operate at right angles to theplane of motion of theformer, are mounted two teaseling-disks E in suitable bearings instandards F, erected upon cross-beams of the lower frame-work. Thesedisks are intended to cross-nap the cloth as it comes from under theaction of the rst napping-cylinder, it having been napped by it in thedirection of the warp ot' the cloth, so `that when the latter is broughtto the second cylinder it will, in-

stead of being napped in thesame line as the last, be submitted to theaction of teasels operating at right angles thereto, whereby the processis materially hastened and the quality and finish of thev goodsenhanced, from 'the fact that both the warp and the woof sential tocross-nap over the whole width may so arrange them as to overlap eachother for this purpose, and in such a case, if deemed advisable, threeor more may be used instead of two; or, instead of using disks or wheelswith teasels secured in the usual manner to Atheir peripheries, anendless apron may be arranged between the cylinders B, having theteasels secured thereto, and driven and guided in any convenient mannerover rolls for the purpose.v This plan may be deemed best by those whoconsider it necessary to cross-nap over the whole width of the cloth,while those who consider it unnecessary to cross-teasel the .centralpart of the web of cloth will prefer to use the teaseling disks orwheel.

To theinside of the side beams of the framework upon which the cylindersB are mounted are secured the inner ends of semicircular slottedguideways G-four in number-arranged one at each head of the cylinders.

Through the slots of these guides pass bolts f, which secure thecarriages g thereto, having lugs projecting therefrom, on which aremounted rolls h, which confine the cloth to the action of theteaseling-cylinders, the forward cylinder being provided with two rolls,each of which is capable of adjustment by means of a rack formed ontheexterior periphery'of every carriage, each of which takes into apinion t', mounted upon either end of a shaft j, by the turning of whichthe carriage is caused to traverse upward or downward in the slot of theguide G, as the case maybe, for the purpose of raising or lowering bothends of the rolls simultaneously, the object of which is to loosen orconfine the cloth more closely to the action of the teasels, as maybedesired; or, in the event of one side of the cloth becoming morespeedily napped than j the others, which not infrequently happens fromdifferences in the quality of the teasels that side of the rolls nextthe finished side I may be raised to loosen it, while the other is keptin lclose contact with the teasels until finished. Upon the rearcylinderis arranged into rack-wheels f', secured upon the shafts j. Upon theplatform H is placed the cloth to be mapped, it being curved at itslower eX- tremity, so as to throw up the lower edge of the cloth andrender it easier Ato be fed and jointed, so as to preserve this positionas the platform is more or less inclined, the outer end of the latterbeing supported upon adjustable lugs for this purpose. One end of thecloth is then passed over two straightening-beams I, which may be somade as to approach or recede from each other, as may be desired, theybeing slightly rounded on their outer edges in order to take out anywrinkles or creases in the cloth, which is then conducted over thecylinders B, between them and the rolls h, and made to turn round adraw-roll J, thence round another K, having a pinion l, gearing into apinion m of the former, thence over the roll L, and from it over thefriction-rolls `M and round the draw-roll N at the farther end of themachine, from which is is conducted down between the rolls of the folderO, where it drops` upon the platform and is there connected with theother end of the cloth, so as to form an endless belt. The rolls 7Lbeing then properly adjusted, the machine is ready to commenceoperations by changing the belt from the loose to the fast pulley P andcommunieating motion to the latter, so as to cause it to revolve inopposite direction to the motion of the cloth, as indicated by thearrows, the folder being operated by a pitman-rod Q, attached to a cranksecured to the shaft of the draw-roll n. As the first cylinder Brevolves it communicates motion to the second by means of a belt passingaround pulleys R and S, secured upon their shafts, respectively, motionbeingalso communicated to the teaseling-disks E in such manner as tocause them to revolve in an outward direction by means of a spur-wheelT, secured upon the shaft of the first cylinder between the pulley andthe frame through suitable intermediate gearing and the bevel-wheelssecured upon their shafts. Then the cylinders both rotate in onedirection, the spur-wheel U, in order to make the draw-rolls revolve inthe proper direction, is made to gear with the small wheel n, mountedupon the same shaft as the spurwheel V, which receives motion from thepinion o on the shaft of the cylinder, as shown in Fig. l; but whencaused to rotate in different directions the spur-wheel is then throwninto gear with the pinion p, as shown in Fig. 3, for the same purpose,by means of the lever W, which is jointed to the upper end of thestandard X, upon which the spurwheels n and p are mounted, its lower endbeing mounted upon the shaft of the first cylinder in such manner as tobe free to oscillate thereon. Into the lower side of this lever are cutnotches which engage with a catch secured to the standard of the frame,

by which-they are kept securely in position.

Y is the belt which communicates motion to the draw-rolls.

l Having thus described our invention, what we claim as new, and desireto secure by the gig-rods a to the cylinders, for the pnr LettersPatent, is poses set forth.
